Others have explained why you shouldn't do this.

If you want to bypass some redirection in the rest of your package's
build system, you could stash a copy of stderr in fd 3 or 5 or
something (eg, in the rules file, with 3>&2), and then write to fd 5.

But perhaps more information would enable us to give better advice.

Thanks,
